如何表现unittest.mock.call单元测试(第二章)

如果我没听错的话,你想看看电话是否接通了 mock_calls . assert_called_xxx 已创建实例上的方法:

@mock.patch('mymodule.SomeClass')
def test1(mocked):
    inst = SomeClass()  # inst == mocked.return_value
    inst.__str__.assert_not_called()

    # use this if you don't have inst
    mocked.return_value.__str__assert_not_called()

    print(inst)
    inst.__str__.assert_called_once()
    mocked.return_value.assert_called_once()
    mocked.return_value.__str__.assert_called_once()

call().__str__ mocked ,你查一下 __str__ mocked.return_value ,这是 call() .

call.__str__()

assert 'call.__str__()' in [str(c) for c in inst.mock_calls]

或者,如果你想在课堂上检查:

assert 'call().__str__()' in [str(c) for c in mocked.mock_calls]
